Chapter 1 Preparation — Precautions for use

rrLCD panel

ffThe LCD panel is precision-made. Note that in rare cases, pixels of high precision could be missing or always lit. Note that such phenomena do not indicate malfunction. If still images are projected for a long time, a residual image may remain on the LCD panel. Note that the residual image may not disappear.

rrOptical parts

When the operating environment temperature is high or in environments where lots of dust, cigarette smoke, etc. is present, the replacement cycle of the LCD panel, deflection panel and other optical parts may be shorter even if used for less than one year. Consult your dealer for details.

rrDo not move the projector or subject it to vibration or impact while it is operating.

Doing so may shorten the life of the built-in motor.

rrLamp

The light source of the projector is a high-pressure mercury lamp.

A high-pressure mercury lamp has the following characteristics.

ffThe luminance of the lamp will decrease by duration of usage.

ffThe lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or degradation due to cumulative runtime.

ffThe lamp life varies greatly depending on individual differences and usage conditions. In particular, continuous use for 12 hours or more and frequent off/on switching of the power greatly deteriorate the lamp and affects the lamp life.

ffIn rare cases, the lamps burst shortly after projection starts.

ffThe risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit regularly.

(“When to replace the lamp unit” (x page 133), “How to replace the lamp unit” (x page 133)) ffIf the lamp bursts, gas contained inside of the lamp is released in the form of smoke.

ffIt is recommended that you store the Replacement Lamp Unit as a contingency.

rComputer and external device connections

ffWhen connecting a computer or an external device, read this manual carefully regarding the use of power cords and shielded cables as well.

Disposal

To dispose of the product, ask your local authorities or dealer for correct methods of disposal.
